identify the study design described in each of the following paragraphs and describe why you selected this study design. For each study, describe (do not just list) one strength and one limitation. The strength and limitation must be specific to the scenario described, not about the study design in general. Your responses must be in complete sentences. A study was conducted to evaluate the relationship between sleep duration and disturbance, and body mass index. Five hundred graduate students from a large university in California completed a survey during the first week of class in the fall 2018 semester. The survey included questions about demographic and socioeconomic characteristics, sleep patterns, weight, height, and physical activity. Study design: Strength: Limitation: Epidemiologists wanted to investigate the incidence of hepatitis C virus (HCV) infection among people who inject drugs. In 2018, they identified a group of people who did not have HCV and started to use the syringe exchange in in 2010. The researchers used records maintained by the syringe exchange program to determine how many participants became infected with HCV between 2010 and 2015. Study design: Strength: Limitation:
